Abstract

Det er beskrevet en fremgangsmåte for fremstilling av titandloksyd ved sulfatfremgangsmåten, hvorved den ved vasking av hydrolysatet dannede væsken fraksjoneres og de fortynnede fraksjonene tilbakeføres l prosessen, mens den relativt konsentrerte tynnsyren tilføres til en avhendlngsprosess.A process for the preparation of titanium oxide by the sulphate process is described, whereby the liquid formed by washing the hydrolyzate is fractionated and the diluted fractions are returned in the process, while the relatively concentrated tin acid is added to a disposal process.
